Olympus Tough TG-5

Why use a digital compact camera (aka point and shoot) when traveling, rather than a mirrorless interchangeable lens camera (ILC) or a smartphone?

I can see two reasons:

a better size-reach combination – only a point and shoot like this Sony HX-60 can offer a 720mm full-frame equivalent focal length at the long end and still be pocketable;
a unique size-ruggedness combination – only a rugged compact point and shoot like an Olympus Tough TG can be carried around all the time, without fear of dust, sand, water. If it gets drowned, crushed or falls in a crevasse, it’s not so much of a big deal. You don’t need it to authenticate to your employer’s VPN, and you don’t store your electronic plane tickets on it. And if you have to replace it, a similar camera will only cost you a fraction of the cost of an ILC or a smartphone on the second hand market.

*The 30x zoom has no equivalent in APS-C or full frame camera systems*

Conventional, long zoom (non-rugged) point and shoot sometimes have relatively large sensors (up to 1in) and a well designed telescopic lens; they offer an impressive image quality, but their motorized telescopic zooms with their retracting lens cap won’t take sand, rain or a fall to the floor lightly.

*On long zoom compact cameras, the lens is protected by a group of retracting blades. You don’t want a grain of sand or a few drops of water to make a mess of it.*

What constraints Image Quality on the Olympus TG-5?

High level, the Olympus TG-5 and its close derivatives the TG-6 and TG-7 deliver a pretty good Image Quality (IQ) for rugged cameras, but are limited by the small size and resolution of their sensor (1/2.3in and 12 Megapixel respectively), and the design and implementation of the lens, a folding internal optic.

That being said, if you’re intended to extract the maximum image quality from the TG-5, it’s important to understand how the camera controls the exposure parameters, and aperture in particular.

*On the Olympus TG, the lens is hidden behind this blade of glass (a decorative bezel normally hides the bayonet over which accessories can be mounted)*

Very few compact cameras (and it was also true at the time of film) use a conventional iris for a linear control of the aperture, with the well known sequence of stops (f/2.0; f/2.8; f/4, f/5.6, f/8, … and so on). In a typical compact camera, aperture control is often performed by the shutter. This design comes with its own set of limitations: only a few aperture values can be selected, and they’re not available with all shutter speeds.

On the TG-5, the maximum aperture of the 25-100mm zoom (full frame equivalent) varies between 2.0 at the widest angle and f/4.9 at the longest focal length (it’s a sliding aperture lens). In order to limit diffraction, the camera only offers two “real” aperture settings (f/2.0 and f/2.8 at 25mm), with higher values (up to f/8 at 25mm) being simply simulated by a Neutral Density (ND) filter. Therefore, image quality will peak at f/2.8, and stopping down beyond won’t improve it (IQ could even be marginally worse because of the ND filter) .

If you decide like me to travel with a Olympus Tough TG-5 (or TG-6 or 7), how to extract the best Image Quality from the camera?

IQ is all relative. If pictures are to be viewed on a social media app installed on a smartphone, the TG-5’s Image Quality is more than adequate. Color balance, exposure, focus, dynamic range are spot-on. Images uploaded to social networks are generally downsampled to a resolution of 3 to 4 million points, a far cry from the 12 Mpix of the Olympus sensor, and not enough to start making the performance limitations of the lens and the heavy hand of the JPEG rendering engine noticeable.

But if the final destination of your image is a 8x11in print, or an 8k monitor, the weaknesses of the lens and the aggressiveness of the sharpening algorithm will become visible, unless you follow a series of steps to ensure the camera always delivers its best.

Olympus Tough TG-5 – how to get the highest quality images:

*The Tough TGs are all available in black and in red. TG-4 on the left, TG-5 on the right (with a JJC UV filter mounted on the accessory adapter*).

Read the manual – The Olympus TG-5 may be a point and shoot, but it’s a highly configurable, and therefore relatively complex camera. Settings are dispersed across multiple menus, and navigating them is unfortunately less than intuitive. In your quest for the best IQ, you’ll have to understand how to save your images as RAW files, how exposure memorization and correction work and after the picture has been shot, how to review and adjust some of the technical parameters. So, read the manual.
If you don’t want to read the dreaded user manual (who does?), ask precise questions to your favorite AI chat application. AI is getting very good at answering questions about cameras and photography, most of the time. ChatGPT 5, for example, combines the information and the test results it gets from DPR, Imaging Resource and Photographyblog with customer feedback collected on forums to provide detailed and mostly exact answers.
Shoot RAW. If you’re really interested in maximizing IQ, it’s definitely much better to shoot RAW and fine tune Clarity, Dehaze and Sharpening in a dedicated image editing app.
Use the sensor where it’s at its best, at 100 ISO, taking advantage of Olympus’ image stabilization capabilities to operate at low shutter speeds.
ChatGPT 5 recommends shooting in A mode (Aperture Priority) and selecting an aperture of one stop above full aperture (that would be f/2.8 at 25mm, which slides to f/6.3 at 100mm) for best performance. That’s the aperture where the lens is the best, but in A mode you are in charge and have to keep an eye on everything (on the shutter speed in particular).
In the real world, the Program P mode does more or less the same job as the A mode – at 100 ISO, for instance, the program sets the aperture at f/2.0 as long as the shutter speed has not reached 1/100s, then steps up to f/2.8 and remains there if possible.
The camera comes with a long list of scene modes – the Scenery/ Landscape scene works well with static subjects when traveling, and I use it often – and it appears to keep the aperture at f/2.8 as much as possible. There are other interesting scene modes – use them if they get you the result you want. Just be aware that Scene modes don’t let you chose the sensitivity or correct the exposure values.
Finally, the obvious – protect the lens from fingers prints and smudges with an easy to clean UV filter, and from incident light with a lens hood.

Of course, you can’t always work with low shutter speeds at 100 ISO. If your idea of a good vacation is to visit ball parks around the country and shoot the players in action at dusk, maybe the TG-5 is not the camera you need.

Why you should shoot RAW with the Olympus TG-5: an example.

*Calvi, Pointe de la Revellata – enlarged section of a RAW file, (moderately adjusted in Adobe Lightroom Classic).*

The TG-5 can be setup to save an image as a RAW file and as a JPEG simultaneously. The images shown above are two screenshots of “La Pointe de la Revellata” in the bay of Calvi, Corsica, taken while editing in Lightroom Classic.

WordPress is downsampling the images massively, but click on each picture and you will see the screenshots at full resolution. And you will really see a difference between the JPEG and the ORF file. The JPEG (the first of the two) shows a much more pronounced accentuation, which translates into an almost cubist representation of the mountain in the backgroud. The RAW file, below, is more subdued. The full image (exported from RAW) is shown at the end of this blog post.

Will all the Olympus Tough TG cameras offer the same Image Quality?

In the heyday of compact digital cameras, Olympus was proposing three different lines of Tough cameras, with multiple variants in each line. This blog entry only covers the “one digit” Tough TGs, and specifically the TG-5 and its close derivatives, the TG-6 and the TG-7.

I don’t think there is much of a difference between the TG-5, TG-6 and TG-7 – mainly progressive improvements on the video capture side (the photo section is identical). The TG-3 and TG-4 have a different sensor (16 Mpix, with a lower dynamic range and more noise), but only the TG-4 can save RAW files. And all models before the TG-5 have an Olympus proprietary USB port, which will force you to carry around an easy to lose proprietary USB cord to recharge the battery of the camera. To me, a used TG-5 is a very good compromise – they abound on the second hand market (eBay, Shopgoodwill) and can be found for less than $200.00.

As a conclusion

A camera is always a compromise between conflicting design goals, and a compact, rugged, water-resistant point and shoot camera can’t be expected to beat a 60 mpix full frame ILC when it comes to image quality.

From an IQ point of view, the TG-5 is probably the rugged compact camera with the highest potential, and if the photographer shoots RAW and pays attention to the exposure parameters (exposure modes, aperture, ISO), the output will reach a much higher level than what could be expected from a compact camera with such a small sensor.

I regularly keep an eye on Shopgoodwill.com auctions. Looking for the unexpected opportunity. A nice camera for a pitance. It’s not very frequent – I’m surprised by how much people are ready to spend on cameras donated to a charity and sold untested.

Sometimes you are lucky. A good camera gets unnoticed – so poorly described that almost nobody can guess what it really is – or the online auction ends at a time when most people have better things to do, and can not be on line to “snipe”.

There were a few auctions ending on Xmas eve and I ended up being the highest bidder for two cameras – a Canon Photura I’m currently testing, and this black Olympus Tough TG-5. The item was correctly described, was said to have passed some basic tests (both points which are not that frequent at Shopgoodwill) but there was very little competition to acquire it – no bidding war and no absurd high sale price. For a change.

The first thing I did of course was to compare it with the Olympus Tough TG-4 I had bought a few months ago.

*The top plate of the TG-5 (the black camera) with the extra control wheel, the improved zoom command and the GPS (Log) switch.*

What are the differences?

The big difference is the sensor. All Tough TG-x models are built around a 1/2.3in sensor. In the first two models (TG-1 and TG-2), the sensor was a 12 megapixel backlit CMOS. The TG-3 benefited from an upgrade to 16 megapixels, which was carried over to the TG-4. The TG-3 and 4 were criticized for their poor control of noise in the darker areas of an image, and for the TG-5, Olympus reverted to 12 megapixel design. With a pixel pitch of 1.53μm versus 1.33μm for the TG-4 each pixel gets 15% more light. Combined with a more powerful image processing engine (a dual quad core Olympus truepic VIII as opposed to the TG-4’s truepic VII), the TG-5 should offer an improved control over noise and deliver cleaner pictures.

The new 12 megapixel sensor also brings a larger sensitivity range – up to 12,800 ISO to whomever is brave enough to test such a setting on a 1/2.3″ sensor, and the support of 4k video.

The other changes relate to the fit and finish and the ergonomics for the most part – there is now a conventional zoom lever and a new control knob on the top plate, and a switch to activate and deactivate the on-board GPS. And big news, the proprietary Olympus connector (used to charge the camera’s battery) has finally been replaced with a standard USB connector (yes!).

*The new menus are hardly an improvement*

Nothing is perfect, and the menus have been revised. Olympus has gained a bad reputation for its confusing and un-intuitive menus, and proves it’s deserved with the TG-5. On the Tough TG-s, Olympus have given a particular emphasis to what they call “live control”: some important settings are not available through the menus, but only when the photographer is ready to shoot a new picture and presses the “OK” key – a column of options is displayed as an overlay at the right of the image, with the different values that each setting can take displayed on an horizontal bar at the bottom of the picture. It’s the only way to chose the form factor of the images (4:3, 3:2 or 16:9, for instance, or the image quality (RAW, RAW+JPEG Fine, JPEG Low) and so on).

At the same time, additional settings have been added to the conventional menus of the TG-5. Some are obviously useful (like setting the standard and high limits of the Auto ISO sensitivity control, the color space or entering copyright information), but others seem to duplicate (or refine) settings already available in the “live control” mode. And they’re not always available – some options are greyed out when the camera is set to “scene” mode, for instance. To make matters worse, instead of giving meaningful names to the new options, Olympus simply designated them as A, B1, B2, C, and so on. Confusing.

*The TG-5 menus are cryptic (why B1 and B2?)*

Shooting with the TG-5

Are the new sensor and the new processing engine improving the noise situation? Imaging-Resource had compared a new TG-5 with a TG-4 a few years ago ( https://www.imaging-resource.com/PRODS/olympus-tg-5/olympus-tg-5-image-quality.htm) and had mixed feelings about it.

Yes, the TG-5 delivered an improvement, but not as large as the testers had expected. The improvement was particularly obvious in the 100 to 800 ISO range, where the noise reduction algorithm was at the same time much less aggressive and more efficient – resulting in more details and less chroma noise.

In my experience, the TG-4 was producing images with very visible noise in the shadows, even by sunny weather under the tropics, and it was not easy to get rid of it. Any improvement in that area would be welcome, and would justify an upgrade to the TG-5, if it delivered the goods.

I compared the two cameras in the real life and tried to validate the conclusions of Imaging-Resource. Firstly, on both cameras, there is more noise on the Raw files than on the jpegs. Which means that the processing engine does a good job at removing it when it generates jpegs. Secondly, the TG-5’s jpegs show more detail in the shadows than the TG-4. The difference is not huge, but big enough to be visible on the Retina screen of an iPad. So, yes, the TG-5’s pictures look better. And what about the rest of the user experience?

The TG-5’s body is made of a different type of plastic and feels more substantial in the hands. Because it offers more controls (physical like the wheel on the top plate or logical with more options in the menus), the TG-5 does not seem as simple to use as the TG-4, and will require more peeks in the user manual than the TG-4, before the photographer is totally familiar with it.

As a conclusion, I would say that the TG-5 has a higher potential than the TG-4 (more details in the shadows, greater ability to be configured to the preferences of the photographer) – but that it’s also a tad more complicated to use. Although it’s difficult to quantify, the TG-5 seems to deliver better images in more circumstances than the TGs of previous generations could. Not having to carry and use a proprietary connection cable to charge the battery of the camera (and using any standard USB cable instead) could very well be the most significant (and the most welcome) improvement.

In the grand scheme of things

As of today (early 2025), there are very few new compact cameras on the shelves of the resellers, and even fewer which are shockproof, waterproof and adventure ready. The OM System TG-7 is the most competent of those always ready cameras – but like all the previous versions of the Tough TG, it will be limited by its 1/2.3″ sensor.

Premium compact cameras, like the Sony RX100 or the Canon G7X, have a much larger sensor. The same can be said of the iPhone (the sensor behind the 16 Pro Max’s main camera is almost as large as the RX100’s at 1/1.14in). Without even considering the “computational photography” trickery of the iPhone, all are obviously going to yield much better results than the TGs in low light and in the shadows. But the Sony and the Canon are not weather resistant, and their long telescopic zoom makes them more delicate than a Tough TG (you won’t bring them to the beach or on a dusty trail ride), while the iPhone (and similar high end smart phones) are fully automated wizards that can’t compete with a dedicated camera when it comes to ergonomics and flexibility of the settings.

The TG-7 is a very limited upgrade of the TG-6, itself a rather limited upgrade of the TG-5. The improvement in image quality and ergonomics between the three most recent TGs and the previous generations is not huge, but any improvement in the 100 to 800 ISO range is good to take, and if you can find a TG-5 at a reasonable price, my recommendation would be to take it over a TG-4. If only for its universal USB connector.
